SR9009 (Stenabolic) SARM – Uses, Side Effects, and More

Stenabolic, or SR9009, is a compound that appeals to athletes and focuses on improving endurance, recovery, and fat loss. While not one of the most potent substances an athlete can use, SR9009 still has its uses and works particularly well when combined with more powerful compounds.

The lack of human-based research on Stenabolic means there is not much data about what it can do. However, research on lab mice showed improvements in critical areas like exercise capacity and better use of stored fat as energy. Stenabolic may also provide some significant benefits for recovery centered around sleep.

Without the typical side effects we have to deal with when using most SARMs or anabolic steroids, Stenabolic holds a lot of appeal. But is it something you should be using? This PED causes confusion and conflicting opinions in the bodybuilding community for several reasons. But one thing is sure: When SR9009 works as it’s meant to, it works incredibly well. Read on to find out all the must-know facts about SR9009.

What is Stenabolic?

Stenabolic is another compound often referred to as a SARM, but technically, it is not. In scientific terms, it is known as an agonist of Rev-ErbA, but the leading interest for those without a chemistry degree is what SR9009 can do for your performance and results.

SR9009 holds some exciting potential for medical use, but the performance effects are the most interesting. The main benefits and effects of SR9009 that are most interesting to us as bodybuilders or athletes are not directly related to its main areas of medical research interest. As you’ll see, Stenabolic is very similar to Cardarine in many ways, not the least of which is its somewhat unintentional but very valuable effects on performance.

Initial lab studies showed that SR9009 was effective at increasing exercise capacity. It was also found that Stenabolic alters the circadian rhythm in mice. However, as this was experimental research with unknown effects in humans, it’s still not fully understood how Stenabolic would impact the human circadian rhythm, either positively or negatively.

The scientist who created Stenabolic has stated that this compound may have little to no bioavailability in humans when taken orally as it does not make its way into the bloodstream. However, those who use the drug for performance-enhancing purposes often report a high rate of bioavailability, potentially indicating the possible downplaying by official sources of the actual effectiveness and beneficial effects of Stenabolic to discourage use. Despite the lack of official scientific research on its effects on humans, many people use this compound with exceptional results.

Bodybuilders and other athletes who have used Stenabolic have determined that it is very beneficial in some specific areas of interest, mainly in increasing endurance, stamina, and fat loss. As this is a research drug only and is not approved for use in humans, no official manufacturer of Stenabolic takes place. The only way to purchase it is through companies selling it as a research chemical.

A Quick Look at SR9009

• Other Names: SR-9009 (generic), Stenabolic, others.
• Primary Use: Investigational compound for metabolic disorders and circadian rhythm regulation. Off-label use for fat loss, endurance enhancement, and muscle preservation.
• Administration: Oral form (liquid or capsules, sold as a “research chemical”). Typical Dosage: 20-30 mg/day (split into 2-3 doses due to short half-life). Half-life: ~2-4 hours (requires frequent dosing).
• Cycle Length: 6-8 weeks (limited safety data for longer use). Often stacked with SARMs (e.g., Cardarine, Ostarine) or stimulants for enhanced fat loss.
• Benefits: Enhanced endurance and workout capacity (via increased mitochondrial efficiency); accelerated fat loss (especially visceral fat); muscle preservation during calorie deficits; no hormonal suppression (does not affect testosterone or estrogen).
• Side Effects: Insomnia (due to circadian rhythm disruption); appetite suppression; mild headaches or nausea; long-term metabolic or organ impacts (no human safety data); potential liver or kidney strain (anecdotal reports).

Note: SR-9009 is a highly experimental compound with no human clinical trials to confirm safety or efficacy. While animal studies suggest metabolic benefits, its effects on humans are unknown. Risks include disrupted sleep patterns and unstudied organ toxicity. Not recommended for use—prioritize diet, exercise, and proven strategies for fat loss/endurance. If used, strict bloodwork (liver/kidney function) is essential.

History and Overview

Stenabolic is a compound whose creation returns to one man: Professor Thomas Burris. It was developed about ten years ago, but the only available data on its effects is from studies on mice. No clinical studies or trials with human participants have been published. This means we must primarily rely on performance users’ reports and personal experiences to determine the good and bad aspects of Stenabolic.

What was learned in the pre-clinical mouse study included that SR9009 affects the circadian rhythm, which may have similar effects in humans. One of the goals was to research whether Stenabolic could be a potential drug for treating disorders relating to sleep and metabolism. Still, until more research comes to light, we won’t know the full medical potential of SR9009. Along with possible future treatment for sleep-related and metabolic conditions, there’s even some interest in Stenabolic helping address jet lag thanks to its effects in “resetting” the body’s natural circadian clocks.

Professor Burris has also developed SR9011, a Rev-ErbA alpha and beta agonist that is thought to have higher oral bioavailability than SR9009. While it’s not yet as popular or well-known as SR9009 in the athletic community, SR9011 is one to keep an eye on in the future.

Mechanism of Action

As a REV-ERB agonist, SR9009 is a unique compound among those usually chosen by us bodybuilders. The main focus on Stenabolic in pre-clinical research has been its ability to alter the circadian rhythm, which affects our sleep and metabolic function.

Rev-ErbA alpha (REV-ERBa) is one of the two proteins of this type found in its nuclear receptor family, and it was discovered over 30 years ago that REV-ERBa is vital for its role in regulating the body’s circadian clock. Because some other body processes are also impacted or controlled by the circadian clock, these are also regulated to an extent by REV-ERBa. These include pathways related to the immune system and the metabolic system.

So, I know what you’re thinking: These are interesting effects, but how does that make Stenabolic desirable for bodybuilders or athletes? Like Cardarine (which Stenabolic is often directly compared to), the “accidental” benefits of increased endurance and stamina have become evident to many who have used SR9009 as a performance-enhancing compound.

SR9009 sits back in second place in popularity compared to Cardarine, despite the known risks of Cardarine, which Stenabolic does not have (see more on this when I compare these two PEDs later). Why do most people prefer Cardarine over SR9009? Primarily, it comes down to convenience; SR9009 has a very effective mechanism of action, but with a short half-life, it requires frequent dosing throughout the day – making it one of the more burdensome compounds to use.

Effects of SR9009 (Benefits)

Lab studies have shown that SR-9009 improved oxygen consumption, muscle mitochondria, and muscular use of glucose while decreasing liver fat cell formation and body fat storage. Studies on mice showed fat loss over 7 days, indicating this compound works quickly.

SR9009 makes the body more efficient using energy sources, so your athletic performance is much higher than usual. Studies have also shown that the metabolic rate at rest can be raised with Stenabolic, so you store less fat and burn more fat at rest.

SR9009 is a fast-acting compound, and we often use it pre-workout. Effects become noticeable quickly after taking your dose, but most will also start wearing off quickly (see my information about Stenabolic’s half-life below). It’s widely agreed that to get the maximum benefits of SR9009 while training, you should take it about an hour before working out.

Increased endurance

The cardiovascular performance effects of SR9009 are, without a doubt, its most valued benefit. Endurance and stamina are boosted to a very high level, so you’ll want to time your dosage before you work out. Some users of oral Stenabolic can find endurance increases somewhat, but for the most potent effects on stamina and performance, you will want to look at using injectable Stenabolic.

Better sleep

The sleep effects of SR9009 can go one way or the other, but when it’s used right, you should notice an improvement in your sleep (on the other hand, some find that insomnia becomes a problem). To get the full benefits of Stenabolic’s activity on the circadian rhythm, you will want to commit to a healthy lifestyle, which means having a consistent sleep pattern – which will ultimately help your recovery and results.

REV-ERBa agonists are already known to be a potential drug to target the treatment of sleep disorders, with this being one of its primary areas of research^[1]. SR9009 may also help you recover, function, and feel more energized even if you haven’t slept well. Some users find that after sleeping for just 5 or 6 hours while consistently using Stenabolic, they still feel rested the next day and able to perform at a high level.

Fat loss

With the massive boost to stamina and endurance, you’re naturally going to be able to burn significantly more fat than average. But Stenabolic may also directly affect how your body uses and burns fat for energy. After all, altering the circadian rhythm, which is the primary function of Stenabolic, has a well-known impact on regulating the metabolism!

It’s known that SR9009 boosts the rate of metabolism while the body is at rest (in mice, at least), which means you can burn calories even while you’re in a passive state (sitting down, sleeping, and so on). When on a calorie-deficit diet, this can result in noticeably faster fat loss, although it won’t be as significant as you can get with a dedicated fat burner compound.

Cholesterol support

SR9009 will have the opposite effect on cholesterol of many SARMs and steroids, in that Stenabolic can improve your HDL levels and decrease LDL levels. Studies have shown that SR9009 can reduce cholesterol and triglycerides^[2]. It’s worth noting that Cardarine is also well known as a compound that can decrease cholesterol and is often used as a cholesterol-supportive compound in a stack. Users who want an alternative to Cardarine to support cholesterol can find Stenabolic an effective option.

Anti-inflammatory

Multiple studies have revealed SR9009’s anti-inflammatory effects on different areas of the body. While we can’t pinpoint exactly what types or severity of inflammation in humans Stenabolic could help reduce, this is always a welcome effect, no matter how minor.

Stenabolic is as helpful for its physical benefits as for its positive effects on the mind, which will ultimately help improve your workout capacity and keep you focused. Sleep quality, fat loss, and increased endurance are where the main benefits of SR-9009 are focused. Fat loss and retaining muscle while cutting are other additional benefits of this compound.

Likely Results

Stenabolic is one of the few compounds with a broad range of benefits beyond the physical ones. But when it comes to your physical results, SR9009 is no slouch. You can expect to see quality fat burning due to an improved metabolic rate and a noticeable improvement in your endurance, which will propel your workouts and other physical activity, so you’re naturally going to burn more fat. If you can exercise for longer and at a higher intensity, more calories will burn.

For many people, fat burning is the main reason to use Stenabolic, and your results can be expected to be impressive, but only if you maintain a good quality diet and keep up intensive exercise throughout the cycle. Since you’re likely to eat fewer calories while trying to burn fat during a Stenabolic cycle, losing muscle tissue becomes a significant concern. Stenabolic can help preserve muscle while fat is burning and potentially contribute to muscle gains if you include weight training in your workouts and use other bulking compounds in a stack.

SR9009 Dosing and Administration

Standard dosing of SR9009 will range from 10mg to 40mg daily. Whatever your dose is, consider splitting it into at least a twice-daily administration (but three or even four times can be more beneficial).

Doses

There have been no clinical studies on humans with SR9009, so we have no scientific data on its effective or potentially dangerous doses for people. Minimal studies on rodents often used very high doses, which, on a body weight basis, would be inappropriate for humans to use. So that leaves us with the experiences of people who have long used Stenabolic for performance and have, over the years, determined a dosage range that can deliver the effects we want. Again, I must emphasize that injecting Stenabolic (the preferred method of use) is going to usually require a lower dose than taking it orally. Here’s a general guide to Stenabolic bodybuilding doses for different experience levels:

Beginner

New users might look at using Stenabolic once per day and just limiting its use to a pre-workout compound. Whether this is an effective strategy for lasting benefits is debatable, but in the short term, it can get you used to SR9009’s effects on your training. A 10mg dose about an hour before working out is a good beginner’s strategy.

Intermediate

Once you move to the next level, you’re likely to want to maintain more consistent levels of Stenabolic in your system. This means dosing it twice to three times throughout the day (but try to avoid taking your last dose 5-6 hours before bed). 10mg twice daily (20mg in total) is an adequate intermediate dose that will keep those metabolic effects going. If timed correctly before training, you should see reduced fatigue during workouts.

Advanced

The most advanced users usually take up to 30mg daily; some will even go to 40mg. Splitting it into three doses will maintain levels all day. At a minimum, a higher dose in this range must be divided into at least two administrations, but I prefer three if I do a 40mg daily dose.

The absolute maximum dose of Stenabolic that is considered safe is 50mg per day. For most users, that level of dosage will be beyond what is required, and many users see good results with as little as 5mg daily, which is a good place for new users to start where you can then evaluate the effects of SR 9009 and adjust the dosage as needed.

Most users find a balance at around 30mg daily, and by splitting this into three doses of 10mg three times per day, you maintain optimal levels of Stenabolic and reduce the risk of sleeping issues occurring. Higher doses of Stenabolic may risk inducing insomnia, which is the opposite effect of what you want to achieve when improving your quality of rest, recovery, and sleep.

Bioavailability, half-life, and cycle length

Stenabolic has a very short half-life. The exact half-life isn’t known, but it’s thought to be around four hours. This has made it a compound we will often take as a pre-workout PED. Since it isn’t going to last long, and its effects are directly needed during the workout (more endurance specifically), you can time your dose before a workout to take advantage of the short half-life.

But then we have another big issue with Stenabolic, which concerns how effective it will be. The bioavailability of SR9009 in oral form is thought to be extremely low. It’s so low that it could be close to zero when taken orally. I know what you might think, though: You read about people who use it orally and insist they feel or see significant effects and results. This could be possible. But it could also be a placebo effect. Remember that we’re talking about increased endurance and stamina, not measurable effects like muscle gains.

There’s another possible explanation for users who find that the oral version of SR9009 gives them noticeable results: The product may not be pure Stenabolic! It’s never out of the question that something else has been put into the formula and sold as SR9009!!! Some users suggest that some amount of Cardarine might be substituted into SR9009 by some of the more unscrupulous suppliers (reminding us again why buying from reliable sources is essential). However, far more people have tried using Stenabolic orally, and it has had no effect whatsoever. Without a doubt, bioavailability is very low orally, and for most of us, Stenabolic isn’t worth using in that form.

Yes, most suppliers still sell Stenabolic in liquid and capsule form, and unsuspecting users will buy it and think it will work as well as any oral SARM. But the truth is that for the highest bioavailability, you need to be injecting SR9009. And that won’t be everyone’s cup of tea. Stenabolic cycles can be as short as eight weeks (especially if you’re stacking it with a PED that requires an 8-week cycle), but many users will take it for 12, 16, or even 20 weeks or more. With no suppression or cholesterol impacts caused by SR9009, you won’t deal with those downsides on a longer SR9009 cycle.

Dosing schedule and administration methods

This is where we have to focus on possibly the biggest drawback of using Stenabolic: The need to administer it up to four times per day thanks to that short half-life I just mentioned. Don’t even think about taking Stenabolic just once a day and think the effects will last all day – it will be a waste of time and money.

Some users will take it twice daily and time the doses around training. This can work if you’re disciplined enough to plan your doses properly. In these cases, taking half the dose in the morning and the second half around midday can give you the effects of Stenabolic for the bulk of the day and let it wear down in the evening. It’s not unusual for users to have sleep issues (even full-on insomnia) if a dose is taken later in the evening, which is another good reason to take your first dose as early as possible in the morning.

If you want to try Stenabolic orally (just be prepared for no effects in most cases), take it like a SARM and ideally hold it under the tongue for several seconds before swallowing. But here’s the kicker when it comes to injecting Stenabolic: Injecting SR9009 involves purchasing an injectable form of the compound. Do not go injecting the liquid form of Stenabolic. This is a significant health risk, as the formula is not sterile and can lead to lethal blood infections.

What’s the best way to inject SR9009? I’ve heard of people doing both subcutaneous (or Subq) using an insulin syringe or intramuscular. Again, we don’t have the data to determine the best option. Plan whether you’ll be going for oral or injectable SR9009 before purchasing, and make sure you buy the correct product.

SR9009 Cycles

Just as with dosing, when it comes to the best cycles for Stenabolic, it all comes down to people experimenting and sharing their experiences, as there is no official scientific data out there on how long Stenabolic should be used for best results and what the best other compounds to stack it with are. Experimenting with your own personal dosages and cycle lengths is still a good idea while ensuring you don’t exceed the recommended highest dose or extend your cycles to extensive periods, as any impacts of longer-term use of the compound have still not been determined.

Stenabolic can be used slightly differently from your standard SARM cycles, usually limited to 8 or 12 weeks. Many SR9009 users will consider this PED a longer-term use compound instead of one requiring a specific cycle limit. The lack of known side effects makes it possible to use Stenabolic comfortably for longer, but this will solely depend on your goals. If long-term performance is what you want, it makes sense to extend the cycle, whereas a cutting cycle can be short and sharp, including Stenabolic to boost stamina and fat loss.

SR9009 cycle for men

We will see a lot of different opinions and personal experiences from men who have used SR9009. Those using the oral form will often be disappointed in the results, but I’ve encountered some guys who swear on good results using the liquid.

Stenabolic will often be run at a longer cycle than SARMs. Twenty weeks and longer is not uncommon. Usually, one or more other PEDs will be included in part of the cycle to bring a point of focus to results: Fat burning in particular. At the same time, Stenabolic provides the endurance boost to keep your workouts going high over several months.

Results

The types of results to expect when using SR9009 on a cycle, either on its own or stacked, will always revolve around that very noticeable increase in energy, endurance, and stamina, where you’ll be less tired when training at high intensity.

Men will find gym performance much higher than without Stenabolic, especially when it’s taken around an hour before training (think of it like a pre-workout compound). I’ve often also seen guys noting their mood and well-being have improved on Stenabolic. Again, this isn’t a measurable result either, but it could be related to how SR9009 makes you feel more energized overall.

User reviews

Positive reviews from men about Stenabolic focus on its effects, good results, and the lack of side effects. This is a nice little bonus if you’re used to using just about any other PED that causes troubling side effects (including suppression).

Any negative reviews and comments from men about experiences with Stenabolic will not surprisingly be focused on the fact that there can be no effects at all when oral SR9009 is used. This can be a great shock to guys who had no idea about the bioavailability issues. For this reason, it does pay to do your homework when using a new compound! Some guys report sleep difficulties, even progressing to insomnia, when a dose is taken later in the day.

SR9009 cycle for women

SR9009 is not a hormonal compound, so it’s not thought to bring about any different or additional side effects for female users. The results will be identical to those of male users. Women can expect excellent stamina, endurance, and noticeable fat loss even when not on a hardcore diet (thanks to Stenabolic’s ability to burn calories while you’re at rest).

There’s probably a good reason why Stenabolic is not very popular among women, who will almost always choose other PEDs instead: Relatively few females compared to men have experience with injecting steroids. Without that prior injecting experience, females may be more reluctant to attempt injectable Stenabolic. And with the knowledge that oral SR9009 has low enough bioavailability to make it not worth using, we have very little in the way of anecdotal female experiences with SR9009 to learn from.

SR9009-only cycle

A Stenabolic-only cycle gives you a good introduction to this compound’s specific effects; from there, you can decide what other compounds to stack it with in the future to meet your particular goals. An SR-9009 cycle should run for at least eight weeks, but it’s possible to go up to 12-16 weeks. Start at 5mg-10mg daily, then increase the dosage to 30mg/day if desired.

SR9009 cycle for endurance

SR-9009 excels at boosting endurance as one of its main benefits, so it will appeal primarily to athletes who want to push harder and for longer; this can be anyone from runners to bodybuilders. An effective endurance stack combines 10mg-50mg of Stenabolic with Ligandrol at 10mg daily. Ligandrol boosts strength and healing while increasing the capacity to gain muscle.

Cardarine is another compound that significantly affects endurance, and stacking it at just 10-20mg daily with Stenabolic will provide an impressive performance boost. Each of these stacked endurance cycles can run for between 8 and 12 weeks, with a break of the same length of time to follow.

SR9009 cutting cycle

Cardarine and Stenabolic make for a potent cutting stack combination where fast fat burning is possible, and existing muscle is preserved because Cardarine ensures that muscle is not being used for energy. Stenabolic will boost your focus and stamina, contribute directly to fat burning, and encourage the usage of stored fat as energy; this makes Stenabolic and Cardarine a perfectly matched stack for cutting. For best results, use Cardarine 10mg-20mg per day with a once-daily dose and SR9009 at 20mg to 30mg daily, split into two or three doses, for an 8-week cycle. Neither of these compounds will require any PCT.

My source for SR-9009

The main reason for using Stenabolic is to escalate your endurance to phenomenal levels while promoting fat loss, and you will find that Stena 9009 is designed for the very same thing: Stena 9009 is all about giving you the intense endurance and stamina needed to power through intensive workouts with the number one goal being to torch fat. But even if you aren’t aiming for fat loss, Stena 9009 is incredible purely for athletic performance use – this can be for running, cycling, or any sport where exceptional endurance and stamina get you ahead.

Why I Like It: Stena 9009 only needs to be taken once per day, not four times daily, like Stenabolic.

It’s Worth Noting: Stena 9009 is not a magic weight loss pill; you will lose the maximum amount of fat with a disciplined diet and intensive training program.

Just like SR9009, Stena 9009 allows me to double the time I train, but more importantly, the incredible intensity I can put in for the entire time while staving off fatigue has me burning through calories like nothing else; on top of all that is Stena 9009 working in the background to optimize your metabolism and utilize stored fat for energy. Stena 9009 does all this without the risk of SR9009 and its unknown short and long-term health effects.

It’s not that I don’t like Stenabolic, but it’s a VERY inconvenient compound to use! First, you must take it four times daily because of its short half-life. Who has time for that? Not me. Next, its oral bioavailability is so poor when taken orally that it’s hardly worth the effort. Stena 9009 eliminates all these drawbacks and lets you focus on what matters: Performance enhancement and fat burning. If you decide to use Stena 9009, I recommend buying it here.

SR9009 vs. Other PEDs

SR-9009 is not a SARM or an anabolic steroid. It is generally considered to be less potent than most substances in both of those categories. Still, it has beneficial effects that make it worthwhile to stack with other compounds. Stenabolic will not impact hormones like steroid cycles do, so there is no testosterone suppression. Stenabolic doesn’t require PCT afterward unless you’re stacking it with suppressive compounds. SR-9009 also won’t have any of the side effects that steroids cause. Users of any anabolic steroids will find Stenabolic an easy compound to handle by comparison.

SARMs also differ from Stenabolic as they target specific androgen receptors, whereas SR-9009 does not target these receptors. Some SARMs can cause mild steroid-like side effects, but again, this is not a factor when using Stenabolic. This can make SR-9009 an attractive starting option for those who are brand new to using performance-enhancing compounds and who may be nervous about the side effects of steroids and some of the more powerful SARMs. However, what SR 9009 does have in common with all SARMs and anabolic steroids is that it is banned and prohibited in professional sports and by world doping organizations.

There are dozens of SARMs, steroids, and other types of PEDs we can compare Stenabolic to and weigh up the pros and cons to decide on what’s better to use. I want to look at a few of the more commonly asked-about comparisons and how SR9009 stacks up against some of the most popular PEDs like Cardarine and Anavar:

SR9009 vs. Cardarine

Cardarine is so similar to SR9009 that they are often directly compared and even substituted.

Stenabolic has one benefit over Cardarine: None of the pre-clinical studies showed SR9009 as a cancer risk. That reason alone can turn many of us straight onto SR9009 and away from Cardarine. But then there’s this: Stenabolic needs to be injected to get the same effects and results as oral Cardarine. Otherwise, Cardarine is superior to oral Stenabolic. What about stacking these two? You can stack Cardarine and Stenabolic to double up on the benefits (see my description of this stack below).

SR9009 vs. Anavar

Anavar is a popular oral steroid for both bodybuilders and athletes. Still, it’s especially valued by female users for cutting and contest prep, thanks to its relatively mild side effects at low doses (as far as steroids go).

Would a female be better off using Stenabolic or Anavar? Anavar will provide more muscle gains and more strength than Stenabolic. Both will give excellent endurance and cardio performance, but Anavar does run the risk of virilizing side effects if used for too long.

Regarding male Anavar users, one advantage of using SR9009 instead is eliminating the need to run a testosterone base thanks to Stenabolic being non-hormonal and not suppressive. Males will also need PCT after using Anavar, but this isn’t required with SR9009. Oral Anavar is a liver-toxic compound, whereas SR9009 may potentially benefit the liver.

So, while I often see people asking whether one or the other is a better choice, I would leave Anavar to females who want a more hardcore cycle while being prepared to deal with harsher side effects than SR9009. As for males, Anavar is often thought of as not worth using at lower doses, and at higher doses, you will be facing some substantial side effects, which you won’t have to deal with at all with Stenabolic.

Stacking SR9009

Stacking SR9009 will provide a solid support base for a cutting or recomp stack, mainly by boosting your athletic capabilities with its well-known endurance and stamina effects. You can then choose the PEDs you stack it with based on a specific goal you’re trying to achieve: Fat loss, contest prep, cutting, recomp. Even a bulking cycle can include SR9009 with the right approach.

SR9009 + Cardarine (cutting/performance stack)

Why choose between Stenabolic and Cardarine when you can stack them? Well, mainly because many of us don’t feel comfortable using Cardarine for well-known reasons. But if you’re happy to use Cardarine, consider this the ultimate non-SARMs cardio stack!

Benefits

• Massive endurance and stamina
• Fat loss
• Mental and physical energy
• Improved sleep
• Cholesterol support
• Muscle maintenance

Dosing

• Cardarine: 20mg daily
• Stenabolic: 20mg daily
• Cycle length: 6-8 weeks, with Stenabolic, extended to 16 weeks or more if desired.

Possible Side Effects

• Headaches
• Insomnia
• Cancer risk of Cardarine

If fat loss is your goal, losing 10 lbs or more on this stack over eight or more weeks is possible. Keeping Stenabolic going for the longer term will cause you to lose more body fat, but diet and exercise will play a huge role. You should find it easier to retain existing muscle, and the sleep benefits can have you feeling more rested and energized throughout the day, even if you don’t get an ideal night’s sleep. No PCT is required from this stack as neither compound is suppressive.

SR9009 + Ostarine (cutting/recomp stack)

Adding Ostarine to the stack will help you build and retain more muscle, even helping you break through a plateau mid-cycle. With the right strategy, this cycle can have you both losing some fat while gaining muscle and achieving a toned physique.

Benefits

• Maintain muscle and strength on a calorie deficit
• Fat loss
• Endurance and stamina boost
• Cholesterol support
• Increased bone density
• Faster recovery

Dosing

• Ostarine: 20mg daily
• Stenabolic: 20mg daily
• Cycle length: 12 weeks

Possible Side Effects

• Testosterone suppression
• Increased cholesterol
• Possible liver toxicity from Ostarine

Fat loss, muscle maintenance, stamina, and overall cardio performance will significantly improve. Even if you’re on a strict calorie deficit, you should see your strength levels maintained and even boosted with Ostarine. With a simultaneous gaining of muscle and body fat loss, this is an effective recomp cycle, or it can be run as a pure cutting cycle. Ostarine is known to raise cholesterol somewhat, but SR9009 can counteract this to an extent. Bloodwork is recommended if you have concerns about cholesterol levels.

Note: Ostarine may cause moderate suppression in some men. Only bloodwork will be able to reveal the status of your testosterone. However, if PCT is required or desired, a basic Tamoxifen PCT for four weeks (20mg/day for three weeks, 10mg/day for week 4) will typically be sufficient.

SR9009 + RAD-140 (bulking/recomp stack)

This is a more unusual stack, but with RAD’s differing mechanisms of action (RAD-140 is a true SARM), you can get some good synergy and results with the overall goal of being able to build significantly more muscle than you could on the two other stacks I’ve detailed above.

Benefits

• Significant muscle gains
• Strength gains
• Some fat loss
• Endurance and stamina
• Increased bone density
• Fast recovery

Dosing

• Stenabolic 20mg daily
• RAD-140 10mg daily
• Cycle length: 8-week limit for RAD140; Stenabolic can be used for 16-20 weeks if desired.

Possible Side Effects

• Testosterone suppression
• Insomnia
• Raised cholesterol
• Hair shedding

RAD-140 is a dry compound, so this cycle can result in excellent body recomposition, with muscular definition and vascularity being prominent. Simultaneous fat loss is possible, especially if you take advantage of Stenabolic’s cardio effects by including more training in your workouts. RAD-140 can have a more substantial negative impact on your cholesterol. Remember that the Stenabolic’s positive cholesterol effects may not necessarily be offset (therefore, consider including cholesterol-supportive supplements and dietary changes on-cycle). PCT will be required when using RAD-140 above 5mg daily. Clomid or Nolvadex for four weeks at standard doses is usually sufficient, with HCG rarely needed.

SR9009 PCT

One of SR9009’s appealing attributes is that it is not a suppressive compound. Because Stenabolic is a REV-ERBa agonist, it has no hormonal effects and doesn’t impact your testosterone production or function. If you’re stacking SR9009 with any suppressive compounds, post-cycle therapy will almost always be needed for males.

SR9009 Side Effects

SR9009 is remarkably side-effect-free for most users. That doesn’t mean you won’t experience any unexpected side effects. After all, there is still much to learn about Stenabolic’s effects, and individuals will always have different responses to compounds.

There is only one recognized side effect of SR9009 related to sleep. Stenabolic alters the circadian rhythm, which is our body’s natural clock. This alteration will affect people differently, but most commonly, if an SR9009 dose is taken too late in the day, you might find it difficult to fall asleep or stay asleep. In the most severe cases, insomnia can develop. This can almost always be avoided by taking your doses earlier in the day and setting a limit for the timing of your last dose (according to your schedule and when you usually sleep). My recommendation is to avoid taking a dose of SR9009 within no less than 6 hours before going to bed.

What about testosterone suppression? As a non-steroidal and non-hormonal compound, SR9009 does not affect your testosterone function. It will not reduce circulating testosterone or suppress testosterone production. You don’t have to think about PCT when using Stenabolic alone.

There’s more: Usually, taking oral SARMs or steroids will result in some degree of stress to the liver, including a high risk of liver toxicity with the more potent compounds. However, taking oral SR9009 doesn’t pose a danger to the liver. SR9009 may even have benefits for liver health. One study on mice found that SR9009 improved overall liver health and suppressed liver damage and inflammation^[3]. Women users of Stenabolic also do not need to worry about any masculine trait development, which means both male and female users can safely use Stenabolic without concern for side effects.

SR9009 Supplement

Stenabolic is a mysterious compound with only a tiny amount of research on mice! SR9009 comes with potentially serious but unknown risks to your health in the short and long term. This uncertainty makes Stenabolic simply not worth the risks. With all this in mind, if you want to go straight to the BEST Stenabolic alternative today, STENA 9009 is the one to check out.

Why I Like It: Stena 9009 is fully bioavailable, unlike Stenabolic, so I know I’m getting 100% of the effects of every dose, which makes all the difference when I’m cutting every last ounce of stubborn fat.

It’s Worth Noting: While Stenabolic’s potentially harmful side effects are still unknown, Stena 9009 is sure not to cause any adverse health effects thanks to its all-natural ingredients.

With Stenabolic being a total pain to use (no oral bioavailability, 4x daily dose needed, and ideally needs to be injected), switching to Stena 9009 is a no-brainer where you want very similar results to Stenabolic with a much more convenient once-daily dose that gets absorbed into your system.

Stena 9009 is powerful enough to use as a pre-comp cutting formula. It will promote significant fat loss – but the best aesthetic results will be gained when you’re already relatively lean, and your muscle definition will be more prominent. With increased blood flow from Stena 9009, you can also see some excellent vascular formation. The endurance and stamina boost is noticeable quickly, and when combined with quicker recovery, you can push yourself beyond the limit to speed up that fat loss.

You might have read that Stenabolic itself is “side effect friendly,” but the truth is that so little is known with next to no research done, and unless people are injecting it, it has almost no effect, either good or bad. On the other hand, Stena 9009 has a zero side effect profile, and rather than make you feel horrible with potential lethargy and sleep problems while you’re dieting, Stena 9009 eliminates fatigue and keeps your energy up even on a serious calorie deficit diet. If you decide to use Stena 9009, I recommend buying it here.

Where to Buy SR9009?

Buying SR9009 is as easy as purchasing any SARM or other non-AAS PED. But before you go shopping, carefully think about HOW you want to take Stenabolic and the possible pitfalls of using the more commonly sold liquid form.

Availability of SR9009

SR9009 is widely available at all the usual SARMs and peptides suppliers. Note the types sold: Many suppliers will stock tablets, capsules, powder, liquid, and injectable Stenabolic. Not all suppliers are created equal! And importantly, cost does not necessarily reflect the quality of your SR9009.

Over the years, some users have suspected that other compounds like Cardarine have been included in Stenabolic products (either intentionally or not), which could explain why some oral SR9009 users see better than expected results from what is an otherwise low bioavailable format of this PED.

What’s my point?

While SR9009 is readily available, you must do your due diligence to find a quality supplier selling high-purity Stenabolic.

Is SR9009 legal?

The performance effects of Stenabolic are well recognized, so it’s listed on the World Anti-Doping Agency (WADA) Prohibited List and is tested for in routine drug testing. This gives it the same legal status as anabolic steroids in the world of professional sports; in other words, it is completely prohibited from being used in competitions.

For the personal user like many of you and me, however, Stenabolic is easy to purchase and use without any legal issues in most countries. Like SARMs and other non-AAS PEDs, SR9009 is categorized as a research chemical. You can legally buy it from online research chemical suppliers. While these sellers must include a statement or disclaimer that Stenabolic is being sold only for research purposes (and not for human consumption), as the buyer, you won’t be checked or investigated as to how you’re using SR9009.

Typical pricing

Pricing of SR9009 will vary according to a few factors:

• Which country you’re in or looking at purchasing it from
• The form: Liquid, capsule, powder, or injectable
• The supplier: Higher prices do not necessarily mean a higher quality product!

Despite the bioavailability issues I’ve covered here, liquid SR9009 is still the most commonly sold and easiest-to-find version. Typically, it will come in a 30ml bottle, measured at a concentration of 20mg/ml, for under $70. Injectable Stenabolic can be found in different strengths, with a standard option being 10mg/64mg per ml. The cost of these bottles will often be around $100.

Capsules and tablets are sold in a range of quantities, and since Stenabolic is often used for much longer cycles than SARMs, you’ll want to plan to work out how many capsules you’ll need. This can be expensive, considering the required 2-4 times daily dosing. A typical pack of 60 x 20mg capsules can set you back to $150.

Most suppliers now promote that their Stenabolic is third-party tested for 99% or 99.9% purity. They will provide the certification, but buyers should always beware: It’s ultimately up to you to decide if these certifications are legitimate, as this is simply an optional action for suppliers rather than a legal requirement.

SR9009 FAQs

What is Stenabolic SR9009?

Stenabolic is known as a REV-ERB agonist, making it neither a SARM nor a steroid but a different type of compound. It is a research compound that was only developed out of experimentation but caught the attention of athletes because of its results in mice tests that showed a significant improvement in endurance and weight loss.

Is SR-9009 a SARM?

Stenabolic is not a SARM even though it is often grouped with SARMs and labeled one by those who sell these compounds. It is usually stacked with real SARMs in cycles as it perfectly complements other compounds, such as those commonly used for bulking, cutting, and boosting endurance and performance.

What is SR9009 used for?

SR9009 is mainly used to boost endurance and aid in sleep quality, which can assist with your recovery. It is also helpful as part of a fat-burning cycle as it encourages stored fat to be used as energy, but it is best combined with other more powerful fat-burning compounds like Cardarine. It’s possible that SR9009 can also have some benefits for cholesterol and inflammation.

How much Stenabolic should I take?

Dosages can range from just 5mg per day to a maximum of 50mg daily. Most people will never see the need to take such a high dose, with the standard dosage remaining in the middle of this range at 20mg to 30mg daily. It is wise to split the dose at these dosages into two or three times daily administration.

How do you take SR9009?

SR9009 comes as a liquid, so there are several options for taking it. It can be taken orally, but bioavailability with this method is thought to be very low. Others might use it as an intramuscular or subcutaneous injection to make it more bioavailable. With a short half-life of four hours, splitting the Stenabolic daily dose into two or even three times daily is ideal.

Is Stenabolic safe?

Stenabolic is generally considered very safe to use at low to moderate doses and for limited periods, with breaks between cycles. No serious long-term effects are known, nor are there known short-term serious side effects. Although SR 9009 is not approved for human use, nor have any studies been done on humans who use the compound, there are no known reports of adverse effects from people using this powerful compound for performance enhancement.

Does Stenabolic require PCT?

You do not need to do any PCT when using Stenabolic because it does not have any effect on testosterone or other hormones. If you are stacking Stenabolic with any other compound that suppresses testosterone, then you will need to do post-cycle therapy as usual; however, it won’t be required if you’re using Stenabolic alone.

Final Thoughts

Although technically not a SARM but a Rev-Erb agonist, Stenabolic is still usually promoted as a type of SARM by most vendors. This compound will appeal not so much to bodybuilders but more so to endurance athletes since studies have shown that it can increase endurance significantly and make fat-burning more efficient. Distance runners are one group who would benefit from the effects of Stenabolic. If stamina, endurance, and fat loss are your main goals, then Stenabolic could be the right compound for you; remember that as this is a fairly new SARM, there is still much to learn about its positive and negative effects.

Although some will still disagree, my personal opinion is that if you’re going to use SR9009, then make it injectable. I find Stenabolic not worth using otherwise, and if you take it orally, there’s a good chance you’re wasting your time (and a stack of cash). Injectable SR9009, on the other hand, delivers some exceptional performance results, and I also like the cholesterol and liver-supportive benefits of this PED.

SR9009 is a good alternative for anyone who doesn’t feel confident using Cardarine. It has its place in some stacks like those I’ve listed above. But I must say that the best results with Stenabolic come when you inject it two or three times each day, and that can get tired real quick – so understandably, many people will look to easier-to-use compounds to take instead.
